Calculation is won in the waste piles.

Core Calculation tips

• Assign waste piles with a purpose instead of dropping cards randomly just because a slot is open.
• Protect cards needed soon on the shorter remaining foundation chains so they do not get buried deep.
• Think about which ranks will become useful next on each of the four interval foundations.
• A tidy waste structure is often worth more than one immediate direct foundation play.
• Because only waste tops are accessible, one careless burial can delay progress for many draws.

Best early priority

Learn the next needed ranks on all four foundations. That makes waste placement much easier because you can judge whether a card is safe to delay or dangerous to bury.

Common mistake

Treating the waste piles as generic storage usually leads to blocked sequence cards and a clean-looking board that is actually unwinnable.
